+* New Transaction framework fixing several Concurrent Modification bugs, and
+  ensuring ACID compliance.
+* Removal of debug code, resulting in significant speedup and lower memory usage.
+* Improved documentation.
+* Added datatypes to XML results.
+* Added support for inserting explicit URIs/Literals in an insert/select query.
+* Found and fixed several resource leaks.
+* Fixed Non-Union-Compatible OR queries (Disjunctions).

+* Fixed class loading bug when a non-system class loader has been loaded.
+* Fixed certain types of queries (like MINUS) failing when intermediate results
